If the perimeter of the hexagon is 72, then each side of the hexagon is 72/6 = 12. Therefore, one side of the square is also 12, since the hexagon and the square share a side, so the area of the square is 12 x 12 = 144 cm.
Each side of the square measures 12 ft.(12x12) is 144.
Area = 12 sq inches so each side is sqrt(12) inches So perimeter = 4*side = 4*sqrt(12) = 13.86 inches (to 2 dp).
That is 6 times the area of a single square of 12 x 12.
A triangle with side a: 10, side b: 8, and side c: 12 meters has an area of 39.69 square meters.
